It could be tire balance under acceleration combined with engine load. When the vehicle runs at a constant speed and load , the "unchange" in the drive-assembly dynamics prevents vibration from ocurring.
Remember here, that this vehicle is a front-wheel drive with "half -shafts" driving the front tires. Worn shocks, tires, half-shafts can all contribute to a vibration.
Think of a top-when it is spun quickly, it will move erratically at first, then, settle out to a smooth stationary spin.
it doesn't
Yes
Run around in circles...
It does't
By making it vibrate faster or slower.
Yes, an object can accelerate without friction. The only thing that is needed to accelerate an object is net force acting on it should not be zero. Then the accleration of body is given by Newton's 2nd Law: F = m*a . For example Rockets in space experience no friction, but they accelerate due to force on them by the exhaust gases.
No, the car will not start.
Because that's the definition of "accelerate". "Accelerate" doesn't mean "speed up", although that's how everybody who rides in a car uses the word. "Accelerate" means "change the speed or the direction of motion, or both".
With, or without a Jaws Of Life tool?
